You can take him out easy in one hit if you have MGX and LR Exa leader with 3 dual race mons. You don't even need them to have a single LB. Just make sure you have 3k+ defense so you can survive until their skills are ready.

Or you could use any pvp attack team that can reach SP and doesn't rely on wild combos. But it'll be sloooooooow

rip.... am not gonna go through the trouble of blb'ing zeedmil, kinda unimpressive, so just gonna get a single copy of that and later use as food perhaps, so i hope i can finish craniumon by the time the event ends (not gonna use batteries :X) got the 1st one on the 1st run and the 2nd one on the 7th run :X
